Having always been fascinated by science, and growing up for some of my formative years near the Harwell Laboratory in Oxfordshire, it was inevitable hat I would go into science as a career. Starting as an assistant scientific officer at Harwell, a BSc and Phd followed, and I moved from nuclear physics over into radiation dosimetry, where since 1995 or so I have been working, mostly with industrial high-dose irradiations but also in medical dosimetry, working with primary and secondary standards in my eleven years at the UK National Physical Laboratory, 2004-2015.Since 2015 I have been in Denmark, at the Risø High Dose Reference Laboratory, now part of DTU Health Technology. Our team here works on measurements including dose maps and calibrations, for irradiations with high-energy electrons and photons, and low energy electrons and X-rays, with dosimetry systems including alanine pellets and thin films, and the B3 radiochromic film originally developed at Risø many years ago. We also hold the Danish national standard for radiation absorbed dose, in our gammacell irradiators, although these are traceable currently to NPL.We also run training courses here or elsewhere, sometimes collaborating with NPL and Aerial at Strasbourg in France, and take part in other training activities and committee work, so that we can be found attending ASTM committee E61 meetings (developing the ASTM standards and guidance documents and helping with the workshops this committee runs every couple of years), Irradiation Panel meetings (developing guidance documents here), and some colleagues attend ISO meetings associated with international standards such as ISO 11137 on the radiation sterilization of medical devices.In my off time, I have in the past few years been sailing and helping maintain (in Spring, there is much scraping and re-tarring of the hull and ropes) the Viking ship reconstructions at the Roskilde Viking Ship Museum, with my favourite ship being Ottar, the ocean-going trader based on Skuldelev 1, preserved in the museum. Sailing these ships is not just fun (and with the 26-plus tonnes of Ottar, hard work!) - it is part of the ongoing research to figure out exactly how the Vikings sailed them; nothing from the period is written down, so it is based on interpretation of inscriptions or the wooden remains excavated by archaeologists of actual ships from a thousand years ago.
